Honda BF150 And BF135 Feature Exclusive Designs And Advanced Technology

2/17/2005 5:18:23 PM

With its BF150 and BF135 outboard engines, Honda Marine has established a new generation of marine engine technology. Featuring advanced inline four-cylinder architecture, they draw from Honda's decades of automotive and racing experience.

The Honda BF150 and BF135 engines, based on the same reliable automotive engine that powers the Honda Accord, CR-V and Element, have been designed and produced with the most innovative, efficient, and reliable engine technology. Designed for fresh or saltwater applications, they feature a unique set of advantages, providing more power and reliability with less noise than other engines in their class. Additionally, low fuel consumption and reduced maintenance over time conspire to minimize overall cost of ownership.

The Honda 2.4 liter, 4-stroke BF150 horsepower (hp) engine boasts VTEC (Variable Valve Timing and Electronic Lift Control) Technology; Honda's exclusive Lean Burn Feedback and Three Way Cooling Systems; Dual Overhead Cam (DOHC) Technology and the exclusive Dual Stage Induction System.

Derived from racing, and first appearing on the Acura NSX supercar, VTEC utilizes two cam lobe profiles to operate the intake valves, delivering both strong torque at low rpms and high rpm horsepower to maximize power and fuel economy, regardless of speed.

Honda's exclusive Lean Burn Feedback system maximizes fuel efficiency by automatically adjusting the air/fuel mix according to speed and load. Its top-mounted Linear Air Fuel Sensor works with the engine command system, delivering maximum fuel economy whether trolling or cruising.

To ensure long term durability, Honda engineers designed the first individual controlled cooling system for outboard engines. The Three Way Cooling System reduces engine heat, allowing the cylinder head to run slightly cooler than the cylinder block, which greatly reduces engine wear.

The Honda Dual Overhead Cam (DOHC) Technology creates more valve lift and greater air flow for higher horsepower. The roller rocker arm generates less friction and wear, resulting in longer engine life. This design, unlike traditional DOHC designs, is easy to adjust and contains no complex bucket shims.

The Honda exclusive Dual Stage Induction System uses a plenum chamber with twin butterfly valves for low speed drivability and high-speed performance. At low speeds, air passes through a long intake runner, increasing low-end torque. At more than 3,500 rpm, shutter valves open to shorten the air's path, boosting air flow for higher horsepower. While other 4-stroke engines use long manifolds to deliver air to the cylinder head, the Honda design maximizes combustion efficiency.

Finally, the BF150 features a 2.14:1 gear ratio; a belt-driven, 40-amp alternator that offers the best charging in its class; an engine oil cooler; stainless steel compartments and a 4-Front Corrosion Protection System to create an extremely reliable and rugged power plant.

Fundamentally the same as the BF150, the powerful, compact 2.4 liter Honda BF135 boasts the Lean Burn Feedback and Three-Way Cooling Systems; Dual Overhead Cam (DOHC) Technology and Dual Stage Induction to make this engine unbeatable in its class.

In addition, the BF135 engine uses Multi-Port Programmed Fuel Injection that delivers a precise amount of air/fuel to each cylinder under all operating speeds and conditions. This means that the boater will experience quick starts, instant throttle response, powerful performance and low fuel consumption.

"The powerful, revolutionary Honda BF150 and BF135 engines are setting the standard in technological innovations for engines of their size," said Robin Senger, Honda Marine Marketing. "Their unique combination of performance, efficiency, and value is really resonating with customers."

Like all Honda engines, the BF150 and BF135 exceed the 2006 EPA emissions standards. Both the Honda BF150 and BF135 models come in 20-inch and 25-inch shaft sizes. All new Honda outboard engines for recreational use have a limited, 3-year warranty that is the same on the last day as it is on the first.

Honda Marine introduced the first full line of 4-stroke outboard engines in the United States, setting a new benchmark for ease of starting, quiet operation, and low emissions. Honda's outboards share the same DNA characterized by unparalleled durability, quality, and reliability that is behind its reputation for legendary automobiles.
With models ranging from 2 to 225 horsepower, the company offers the most ultra-low emissions outboards in the industry as well as complies with the California Air Resource Board (CARB) 3-Star ratings.
